Widen a choice to include foreign fare (5)
I believe the answer is:
nacho
'foreign fare' is the definition.
(I've seen this before)
'widen a choice to include' is the wordplay.
'to include' says the answer is hidden in the clue.
'NACHO' is hidden within 'widen a choice'.
(Other definitions for nacho that I've seen before include "Tortilla chip topped with cheese and spices" , "Mexican dish" , "Something consumed" , "Mexican bite" , "Foreign fare" .)
